The Blindata Agent does not include this driver: download the vendor JDBC driver and copy the .jar into the agent drivers folder, as described in
Add JDBC drivers.
Driver properties can be added under Advanced settings in the connection wizard.
Prerequisites & permissions
- A Blindata Agent installed with network access to Couchbase.
- The vendor JDBC driver installed on the agent (see Add JDBC drivers).
- A user with
Query SelectandQuery System Catalogroles on the buckets to document.
Set up metadata crawling
- Create the connection to Couchbase on the agent (see Connection settings) and use Test to verify it.
- Create or open the system that represents Couchbase in the catalog and link it to the connection.
- In the CRAWLING tab add a crawling job with strategy JDBC.
- Run a TEST to check the number of extracted objects, then RUN or schedule the job.
The job options and the column aliases of every extraction query are described in the Generic JDBC reference.
